Even though you say the m4 is more accurate, I don't care. In a match or scrim, I always pick up an AK off of a dead T.
It kills with one headshot regardless of armor. I rarely ever spray, but when I do, I rely more on the m4 since the bullet spread is less. Although I do know the spray pattern of the AK in source pretty well.
I usually do 1 or 2 controlled bursts. The m4 will fool you when you get a headshot and your enemy is still dancing around shooting at you.
Nice post dude. I think this should be stickied
Plus, it just goes to show how random that fucking P90 is. Spray at someone's toes and get a headshot.
